Experimental Probability and Theoretical Probability

Front

Experimental probability is________________________

Back

the ratio of the number of times an event occurs to the total number of trials.

Front

Theoretical probability is________________________

Back

the ratio of the number of favorable outcomes to the number of possible outcomes.

Front

If the theoretical probability of an event is 1/4, what does this mean?

Back

There is a 25% chance of the event occurring.

Front

What is the difference between experimental probability and theoretical probability?

Back

Experimental probability is based on actual experiments, while theoretical probability is based on expected outcomes.

Back

30/50 or 3/5.
